Question

Катер проходит по течению реки 60 км за 2 ч а против течения за 3 ч найдите собственную скорость катера и скорость течения реки

Answer 1

1) 60/2 = 30 (км/ч) скорость катера по течению
2) 60/3 = 20 (км/ч) скорость катера против течения
3) 30 - 20 = 10 (км/ч) - скорость течения реки
ответ: 10км/ч

Answer 2

Calculation of the Boat's Speed and River Current Speed

To find the boat's speed and the speed of the river current, we can use the formula:

Boat's Speed = (Distance traveled downstream) / (Time taken downstream)

River Current Speed = (Distance traveled upstream) / (Time taken upstream)

Given that the boat travels 60 km downstream in 2 hours and 60 km upstream in 3 hours, we can calculate the boat's speed and the speed of the river current as follows:

Boat's Speed = 60 km / 2 hours = 30 km/h

River Current Speed = 60 km / 3 hours = 20 km/h

Therefore, the boat's speed is 30 km/h, and the speed of the river current is 20 km/h.
